Management technology

In the first two years of planting, we must strengthen the management of orchards. When the seedlings of Wogan just grow out of spring shoots, nitrogen fertilizer should be added in time to effectively promote the growth of tree tops, and the frequency of fertilization should be controlled at about half a month. When the top of the tree grows to about 20 cm, the heart can be removed, which can help the Vogan tree grow new branches. Multiple coring treatments can make the crown of Wogan tree form rapidly and expand the growth scale of Wogan tree rapidly. Fertilizer can be mixed with water when applying fertilizer, so watering can accelerate the absorption of nutrients by plants. The fertilizer applied in September should be mainly phosphate fertilizer, supplemented by potassium fertilizer and organic fertilizer. In the vigorous growth season, the growth of young trees is promoted by applying Trim foliar fertilizer and organic fertilizer containing trace elements.

Early management

It is very important to manage the orchard in the first two years after planting. When the spring shoots of seedlings grow to 5 cm, topdressing should be started, with nitrogen fertilizer as the main fertilizer, and topdressing should be done once every half month to promote the growth rate of new shoots. When the new shoots grow to 20 cm, the heart should be removed in time to promote branch differentiation. Try to let it sprout 3-4 times in the first year, so that the crown can expand rapidly. When applying fertilizer, the method of water and fertilizer integration can be adopted, and phosphorus and potassium fertilizer are mainly used in September. In 10, phosphate fertilizer and organic fertilizer are the main crops, and leaf dressing and trace elements should be the main crops in the growing season.

Plastic surgery promotes fruit

Wogan grows very fast, so we should pay attention to the cultivation of trees in the first year after planting. After planting seedlings, the stems should be fixed immediately. Generally, about 30 cm is reserved for short cutting to promote branching. After the spring shoots stop growing, the spring shoots over 20 cm should be appropriately cut short. In summer, due to the irregular growth of summer shoots, 20 cm long branches should be cored to prevent long branches from growing in vain. Then, after the new shoots stop growing in summer, the longer new shoots are cut short, some potassium dihydrogen phosphate is sprayed on the leaves to promote the growth of new shoots, and then an appropriate amount of nitrogen fertilizer is applied to promote the germination of new shoots.
